摘要
电容取能电源由于体积小、装置成本低和取能稳定等优势,成为10 kV一二次融合柱上开关的就地取能电源。为了在取电电流限制下提高最大取能功率,基于简化取能模型进行了输出电压和取能功率的电源特性研究,给出了不同补偿关系下的电源特性;通过影响取能功率上限的设计参数分析,得到了最大取能功率下的设计原则;考虑到典型负载如柱上开关的动态特性,进行了负载等效为储能电容器、恒功率负载及瞬时大功率负载下的仿真,其结果表明了不同动态负载下的电源特性,验证了理论计算的电源特性。
Owing to its advantages such as small size,low installation cost,and stable energy extraction,the capacitor energy extraction power supply has become the local energy extraction power supply for pole-mounted switch with primary and secondary fusion in 10 kV power systems.To further improve the energy extraction power under the limitation of drawn current,the power supply characteristics of output voltage and energy extraction power are studied based on a simplified energy extraction model,and the power supply characteristics under different compensation relations are pointed out.The design parameters affecting the upper limit of energy extraction power are analyzed,and the design principle under the maximum energy extraction power is obtained.Considering the dynamic characteristics of typical loads such as pole-mounted switch,simulations are carried out under the equivalent load of energy storage capacitors,constant-power load and instantaneous high-power load,which show the power supply characteristics under different dynamic loads and verify the theoretically calculated power supply characteristics.
